'To all wh o'm, it mag concern:

known that I, SAMUEL Gr. G znnn,

Be. it captain, Ordnance Dept, U. S. Army, a citizen of, the UnitcdStates, stationed at Washington, D. 0., have invented anImprovement inAdjustable Shoulder-Rests, of which. the following is a specification.

The invention described herein may be used by the Government, or any ofits officers oremployeesin prosecution of work for .the Governmennorbyany other person in theUnited States, without payment of any pending Vinafter.

'ed on a hollow Specifically, the improvement resides, z'nt er aha, 1n ashoulder rest having a length-c wise adjustable gun attaching portion,pref ,erably comprising telescoping sections.

The improvement rcsides, also, in an adjustable shoulder-rest piece,slidably mountsheet metal standard, which is shaped in a novelmannerfrom a single piece of material and suitably secured to thegun-attaching portion.

' Theinvention 1s graphically shownin the i accompanying drawings,whichshow an exemplary construction embodymg the underlying principlesof the invention. Like reference characters designate corresponding 7parts throughoutthe several views, Briefly described Figure 1 is a viewin side elevation of my improved shoulder-rest;

Referring, now, in det ailto the drawings: The gun attaching portion'ofthe shoulder-rest comprises, i in this instance, two telescoping tubularmembers, an outer men'iberv .1 and an inner member 2, whereby saidportion is adjustable asto length.

The outer member (shown in detail in Fig. 9) 1S P1QV1d6ClWltl1 alongitudinal slot 3. extending from one end thereof, to. permit ofcontraction of the member by suitable clamping 1neans, c ompr'ising, inthisinstancefa strap 4 preferably welded to the exterior of the tube 1and carrying a pivoted clamp screw 5, carrying a clamping nut 6, wherebythe tube may be clamped around a gun. The clamping means describedformsno part of the joresent inven- 'tion, since it is fully shown anddescribed in my said co-pending application.

Thetube 1 is also provided with a second longitudinal slot 7 throughwhich projects a threaded clamp bolt 8, which passes, also, through anaperture 9 in thetinner tube 2. On the bolt 8 is screwed a wing nut 10.Between the nut andthe tubel and between the head ll of the. bolt andthe inner tube 2 are disposed washers 12-12, each having, as

shown in Fig. 2, a curvilinear face conformmg to andfbearlng against thecircumference of the tube.

"It will thus be noted, that when the nut 10 is loosenechthe tubes 1 andQ may be moved relativeto each otherto lengthen or shorten thegun-attaching portion of the nels or slide-ways 15-15 shoulder-rest, andthat the tubes may be secured in the desired adjusted position bytightening the clamping nut.

The inner tube 2 is suitably secured to a standard 13 (shown in detailin Figs. 5 and 6) which, from the standpoint of practicability inmanufacturing and lightness in weight, is preferably of sheet metal cutout and bent u from a single blank, and the longitudinal over-lappingends lll welded together.

Two opposite sides of the elongated hollow sheet metal member thusformed are bent or crimped in, as shown in Fig. 6, to provide twolongitudinally-extending chanto guide a slide 16, constituting theshoulder-rest piece (hereinafter more particularly referred to), in itsmovement on said standard 13. Each of said crimped-in portions isprovided with a longitudinally extending slot 17, for a purposepresently appearing.

Each crimped-in portion, at each end thereof, carries a tongue or lip18, the two tongues, at each end, being bent toward each other so thattheir free ends meet, as clearly shown in Fig.

be welded together. By this peculiar con struction, the hollow standardis braced and strengthened against collapse or buckling inward of thewalls thereof. It will be noted that the standard 13 is in one piece andthat it is simple and practical from a mechanical standpoint, being easyand cheap to manufacture and light in weight, while possessing therequisite strength and durability.

The means for securing the tube 2 to the standard 13 may obviously bevariable. An exceedingly simple and efficient form is shown in thedrawings and will now be described.

A collar 19 (shown in detail in Fig. 11) is provided with a lateralcircumferential flange 20, which may be welded to a side wall of thestandard 13. The collar may obviously be threaded interiorly, and, insuch case, the tube 2 would, of course, be exteriorily threaded at itsend, so that it may be screwed into the collar. However, I prefer tomake the collar unthreaded and to slide the end of the tube 2 therein,and then weld the collar thereto.

Adjustably supported on the standard 13 is the slide 16, constitutingthe shoulder-rest piece, shown in detail in Figs. 7- and 8. The slide ispreferably formed from a single piece of material and comprises two sidewalls, which are crimped or bent inward, as shown, to formlongitudinally-extending ribs or tongues 2121, which fit in thecomplemental slide-ways 1515 in the standard 13, whereby the shoulderrest piece is guided in its sliding movement on 6. Such meeting endsmay' the standard. The shoulder-rest piece is 6 provided with a wing 22havln a curvilinear face 23, to fit the shoul er of the user, and whichface may be transversely serrated, or otherwise roughened, to preventslipping when the shoulder-rest piece is in use.

The crimped-in portions 2l-21 are r0- vided with diametrically oppositee orations 24, through which projects a t readed clamping bolt 25carrying a wing nut 26, and which bolt passes through the slot 17 in thestandard 13, whereby the ribbed 0rtions 2121 of the slide may be tig tlclamped against the standard and the slidz or shoulder-rest piecethereby securely frictionally held in adjusted position.

Having described my invention, what I claim as new and desire to securebyLetters Patent, is

1. A shoulder rest comprising a 'gun attaching portion adjustable withreference to length, a standard carried thereb positioned transverselythereof, and a sli e, constituting a shoulder-rest piece, adjustablysupported on said standard. v

2. A shoulder-rest. comprising a gun at taching portion in twotelescoping sections positioned transversely thereof, a standard carriedby one of said sections, and a slide, constituting a shoulder-restpiece, adjustably supported on said standard.

3. A shoulder-rest comprising a gun attaching portion intwo telescoplngsections, one of said sections being provided with a longitudinal slotextending from one end thereof, and with a second longitudinal slot,clamping means encirclingsaidfirst mentioned slotted portion forcontracting the same around a gun, clamping means passing through saidsecond slot and through the other section. for securing saidsections inadjusted position, and astandard transversely carried by one of saidsections, and a slide constituting a shoulder-rest piece adjustablysupported on said standard.

4. A shoulder-rest comprising a standard formed from a single sheetmetal blank and bent longitudinally to provide side walls, two of saidwalls being bent inwardly to provide longitudinally extending channels,a slide, constituting a shoulderrest piece, having complemental bentportions engaging said channels, and means for holdin the slide inadjusted position on said stan ard.

5. A shoulder-rest comprising a standard formed from a single plece ofmetal and bent longitudinally to provide sidewalls, two of said wallsbeing bent inwardly to form longitudinally extending channels; means forbracing said standard against collapse, comprising tongues carriedthereby and bent toward each other with their free ends abutting; aslide having complechannels; means for bracing said standard 10 againstcollapse, comprislng tongues carried thereby and bent toward each otherwith their free ends abutting; a slide having complemental bent portionsengaging said channels; and adjusted position on said standard.
